module: ipmi_boot
short_description: Management of order of boot devices
description:
  - Use this module to manage order of boot devices
options:
  name:
    description:
      - Hostname or ip address of the BMC.
    required: true
  port:
    description:
      - Remote RMCP port.
    default: 623
  user:
    description:
      - Username to use to connect to the BMC.
    required: true
  password:
    description:
      - Password to connect to the BMC.
    required: true
  bootdev:
    description:
      - Set boot device to use on next reboot
    required: true
    choices:
      - network -- Request network boot
      - floppy -- Boot from floppy
      - hd -- Boot from hard drive
      - safe -- Boot from hard drive, requesting 'safe mode'
      - optical -- boot from CD/DVD/BD drive
      - setup -- Boot into setup utility
      - default -- remove any IPMI directed boot device request
  state:
    description:
      - Whether to ensure that boot devices is desired.
    default: present
    choices:
        - present -- Request system turn on
        - absent -- Request system turn on
  persistent:
    description:
      - If set, ask that system firmware uses this device beyond next boot.
        Be aware many systems do not honor this.
    type: bool
    default: 'no'
  uefiboot:
    description:
      - If set, request UEFI boot explicitly.
        Strictly speaking, the spec suggests that if not set, the system should BIOS boot and offers no "don't care" option.
        In practice, this flag not being set does not preclude UEFI boot on any system I've encountered.
    type: bool
    default: 'no'
requirements:
  - "python >= 2.6"
  - pyghmi
